NAME

perror − display MySQL error message information

SYNOPSIS

DESCRIPTION

perror displays the error message for MySQL or operating system error codes. Invoke perror like this:

perror [options] errorcode …

perror attempts to be flexible in understanding its arguments. For example, for the ER_WRONG_VALUE_FOR_VAR error, perror understands any of these arguments: 1231, 001231, MY−1231, or MY−001231, or ER_WRONG_VALUE_FOR_VAR.

$> perror 1231
MySQL error code MY−001231 (ER_WRONG_VALUE_FOR_VAR): Variable ’%−.64s’
can’t be set to the value of ’%−.200s’

If an error number is in the range where MySQL and operating system errors overlap, perror displays both error messages:

$> perror 1 13
OS error code 1: Operation not permitted
MySQL error code MY−000001: Can’t create/write to file ‘%s’ (OS errno %d − %s)
OS error code 13: Permission denied
MySQL error code MY−000013: Can’t get stat of ‘%s’ (OS errno %d − %s)

To obtain the error message for a MySQL Cluster error code, use the ndb_perror utility.

The meaning of system error messages may be dependent on your operating system. A given error code may mean different things on different operating systems.

perror supports the following options.

• −−help, −−info, −I, −? Display a help message and exit.

• −−silent, −s Silent mode. Print only the error message.

• −−verbose, −v Verbose mode. Print error code and message. This is the default behavior.

• −−version, −V Display version information and exit.
